Ok for ducks and chickens to eat bunchberries?

Just wondering if it is alright for my guys to eat these. I have a bag of them that I froze, plus my woods are stocked right full of the plants, so I don't really have a choice either way come summer. It's a berry that comes off one of the dogwood plants.

Also, what treats do you guys feed your ducks and chickens. I have been trying new things, but just curious.

Assuming you are talking about Cornus Canadensis, should be fine. All sorts of animals, including birds eat it in the wild.
